Description

Technical Field

[0001] This utility model relates to the field of window cleaning robot technology, and in particular to an edge-assisted rolling device for a window cleaning robot. Background Technology

[0002] Window cleaning robots, also known as automatic window cleaning machines, glass cleaning robots, smart window cleaners, and intelligent window cleaners, are a type of smart home appliance. They can firmly adhere to the glass using a vacuum pump or fan at their bottom, and then automatically detect the distance to the corners of the window and plan the cleaning path with the help of artificial intelligence. Window cleaning robots generally use the force of their adhesion to the glass to drive the cloth at the bottom of the machine to wipe away the dirt on the glass.

[0003] However, in existing technologies, most window cleaning robots detect the distance to the boundary through sensors. But the window cleaning robot only turns and adjusts after its edge collides with the frame. And there are no protective or auxiliary devices at the edge of the window cleaning robot. After long-term operation, the normal service life is easily affected by collisions. Therefore, a solution is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology: most window cleaning robots detect the distance to the boundary through optical coupler sensors, but the window cleaning robot will only turn and adjust after the edge of the window cleaning robot collides with the frame. However, there are no protective or auxiliary devices set at the edge of the window cleaning robot. After long-term operation, the normal service life is easily affected by collisions.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an edge-assisted rolling device for a window cleaning robot, comprising: a window cleaning robot body; multiple mounting slots formed at the four corners of the surface of the window cleaning robot body; and further comprising:

[0006] Multiple springs are provided at the four corners of one side surface of the window cleaning robot body, and a positioning pin is provided at one end of each spring.

[0007] Multiple mounting bases are movably embedded in multiple mounting slots, and the surfaces of the multiple mounting bases are provided with positioning holes, which are movably fitted onto the surfaces of multiple positioning pins.

[0008] Preferably, the inner walls of the plurality of mounting seats are provided with limiting grooves, and the inner walls of the plurality of mounting seats are provided with dampers.

[0009] The technical effect of adopting the above-mentioned further solution is that the limiting groove opened in the inner wall of the mounting base facilitates the positioning of internal parts, while providing support for the damper.

[0010] Preferably, the output end surfaces of the plurality of dampers are provided with connecting rods, and the plurality of connecting rods are movably embedded inside the mounting base.

[0011] The technical effect of adopting the above-mentioned further solution is that the damper provides a buffering effect on the connecting rod, allowing the connecting rod to move along the interior of the mounting base.

[0012] Preferably, one side surface of the plurality of connecting rods is provided with a shock-absorbing spring, and one end of the plurality of shock-absorbing springs is fixedly disposed on the inner wall of the mounting base.

[0013] The technical advantage of adopting the above-mentioned further solution is that by connecting the two ends of the shock-absorbing spring to the surfaces of the mounting base and the connecting rod respectively, it is convenient to provide a reset function for the connecting rod.

[0014] Preferably, limiting blocks are provided on the surfaces of the plurality of connecting rods at symmetrical locations, and one end of the plurality of limiting blocks is slidably embedded in the interior of the limiting groove.

[0015] The technical effect of adopting the above-mentioned further solution is that the limiting block on the surface of the connecting rod is slidably embedded in the limiting groove, which provides a limiting function for the connecting rod and prevents it from slipping.

[0016] Preferably, the surface bearings of the plurality of connecting rods are provided with L-shaped rods, and the inner wall bearings of the plurality of L-shaped rods are provided with rubber rollers.

[0017] The technical effect of adopting the above-mentioned further solution is that the connecting rod provides positioning for the L-shaped rod, and the rubber roller inside the L-shaped rod can easily contact the window sill to provide an auxiliary rolling effect.

[0018] Preferably, springs are provided on the surfaces of the plurality of L-shaped rods at symmetrical locations, and one end of each spring is fixedly disposed on the inner wall of the connecting rod.

[0019] The technical effect of adopting the above-mentioned further solution is that by connecting the two ends of the spring to the surfaces of the L-shaped rod and the connecting rod respectively, the rubber roller performs a buffering operation when it contacts the window sill.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, by embedding the mounting base along the inside of the mounting groove, when the positioning pin on one surface of the spring is pulled, the positioning pin is disengaged from the inside of the window cleaning robot body. When the mounting base is installed inside the mounting groove, the positioning pin is released, so that one end of the positioning pin is embedded in the inside of the positioning hole, thus completing the positioning work of the mounting base, which facilitates its replacement or maintenance, thereby providing protection.

[0022] 2. In this utility model, when the robot moves and contacts the window sill via the rubber roller, the two ends of the second spring are respectively connected to the surfaces of the L-shaped rod and the connecting rod, causing the L-shaped rod to swing around the circular axis, thus completing a simple buffering operation. In conjunction with the damper and the shock-absorbing spring, the two ends of the damper and the shock-absorbing spring are respectively connected to the surfaces of the mounting base and the connecting rod. When a collision occurs with the window sill, the connecting rod moves along the inside of the limiting groove through the limiting block, while simultaneously performing buffering and shock absorption, reducing the damage to the main body of the window cleaning robot caused by the collision.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Example 1, such as Figure 1-4As shown, this utility model provides an edge-assisted rolling device for a window cleaning robot, including: a window cleaning robot body 1; multiple mounting slots 101, which are formed at the four corners of the surface of the window cleaning robot body 1; multiple springs 102, which are set at the four corners of one side surface of the window cleaning robot body 1, and one end of each spring 102 is provided with a positioning pin 1021; multiple mounting seats 103, which are movably embedded in the multiple mounting slots 101, and the surfaces of the multiple mounting seats 103 are provided with positioning holes 1031, which are movably fitted onto the surfaces of the multiple positioning pins 1021.

[0032] In this embodiment, by embedding the mounting base 103 along the interior of the mounting groove 101, and by pulling the positioning pin 1021 on the surface of the spring-102, the positioning pin 1021 is disengaged from the interior of the window cleaning robot body 1. When the mounting base 103 is installed inside the mounting groove 101, the positioning pin 1021 is released, so that one end of the positioning pin 1021 is embedded in the interior of the positioning hole 1031, thus completing the positioning work of the mounting base 103, which facilitates its replacement or maintenance, thereby providing protection.

[0033] In Example 2, the inner walls of multiple mounting bases 103 are provided with limiting grooves 1032, and dampers 1033 are provided on the inner walls of multiple mounting bases 103. Connecting rods 104 are provided on the output end surfaces of multiple dampers 1033. Multiple connecting rods 104 are movably embedded inside the mounting bases 103. Shock-absorbing springs 1034 are provided on one side surface of multiple connecting rods 104. One end of multiple shock-absorbing springs 1034 is fixedly set on the inner wall of the mounting base 103. Limiting blocks 1041 are provided on the symmetrical surfaces of multiple connecting rods 104. One end of multiple limiting blocks 1041 is slidably embedded inside the limiting grooves 1032. L-shaped rods 1042 are provided on the surface bearings of multiple connecting rods 104. Rubber rollers 1043 are provided on the inner wall bearings of multiple L-shaped rods 1042. Springs 1044 are provided on the symmetrical surfaces of multiple L-shaped rods 1042. One end of multiple springs 1044 is fixedly set on the inner wall of the connecting rods 104.

[0034] In this embodiment, when the rubber roller 1043 contacts the window sill during movement, the two ends of the spring 1044 are respectively connected to the surfaces of the L-shaped rod 1042 and the connecting rod 104, causing the L-shaped rod 1042 to swing around the circular axis, completing a simple buffering operation. In conjunction with the damper 1033 and the shock-absorbing spring 1034, the two ends of which are respectively connected to the surfaces of the mounting base 103 and the connecting rod 104, when a collision occurs with the window sill, the connecting rod 104 moves along the inside of the limiting groove 1032 through the limiting block 1041, while simultaneously performing buffering and shock absorption, reducing the damage to the window cleaning robot body 1 caused by the collision.

[0035] Working principle: In use, the mounting base 103 is embedded along the interior of the mounting groove 101. When the positioning pin 1021 on the surface of the spring 102 is pulled, the positioning pin 1021 disengages from the interior of the window cleaning robot body 1. When the mounting base 103 is installed inside the mounting groove 101, the positioning pin 1021 is released, causing one end of the positioning pin 1021 to be embedded inside the positioning hole 1031, thus completing the positioning of the mounting base 103. This facilitates replacement or maintenance and provides protection. Additionally, when the window cleaning robot body 1 is wiping the window, during movement... When the rubber roller 1043 contacts the window sill, the two ends of the spring 1044 are connected to the surfaces of the L-shaped rod 1042 and the connecting rod 104, respectively, causing the L-shaped rod 1042 to swing around the circular axis, completing a simple buffering operation. In conjunction with the damper 1033 and the shock-absorbing spring 1034, the two ends of which are connected to the surfaces of the mounting base 103 and the connecting rod 104, respectively, when a collision occurs with the window sill, the connecting rod 104 moves along the inside of the limiting groove 1032 through the limiting block 1041, while simultaneously performing buffering and shock absorption, reducing the damage to the window cleaning robot body 1 caused by the collision.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
